What Is a Whole Chicken?

How to Cook a Whole Chicken: A whole chicken refers to the entire bird, minus the head, neck, feet and internal organs, which are typically removed before sale in the UK. Cooking a whole chicken is one of the simplest and most rewarding ways to enjoy this versatile meat, perfect for roasting and sharing.

At Swaledale, our free-range chickens are slow-grown to full maturity (81 days) and reared with the highest welfare standards. Raised with plenty of space to roam and forage, these birds develop naturally, resulting in exceptional flavour and texture. The well-exercised legs deliver proper structure, whilst the breast meat remains juicy and tender.

How Long Does It Take to Cook a Whole Chicken?

Whole chicken cooking times can vary depending on the method and the size of the bird. There’s a common tendency to overcook chicken, often out of caution. In reality, a bird rarely needs more than an hour if cooked from room temperature. This is a crucial step for a properly roasted chicken.

As a general rule, roast at 200ºC for about 20 minutes per 500g, plus an additional 10–15 minutes. The safest way to check doneness is to probe the thickest part of the breast. A reading of 72ºC is the moment to remove the chicken from the oven. Leave it to rest for at least 30 minutes before carving. This allows the juices to redistribute, keeping the meat moist and flavourful.

For extra-crispy skin, pat the chicken dry and salt the skin generously before roasting.

How to Cook a Whole Chicken in the Oven

This is a simple method for cooking a whole chicken in the oven.

  1. Take the chicken out of the fridge three hours before you plan to cook it. Remove all packaging and pat it dry with kitchen paper — rinsing it under the tap isn’t necessary and can spread bacteria. Allowing the chicken to come up to room temperature ensures even cooking and helps keep the meat juicy, especially the breast. Pop it on a plate or in a roasting dish, ready for seasoning.
  2. Preheat your oven to 210ºC.
  3. Season the bird generously, both inside the cavity and over the skin, with sea salt. Place a quartered lemon, half a bunch of thyme, and a halved head of garlic inside the cavity.
  4. Drizzle a little olive oil over the bird and rub it into the skin.
  5. Place the chicken in a suitably sized roasting tray, then cook in the oven for 10 minutes.
  6. Reduce the temperature to 180ºC and cook for a further 40–45 minutes. After 20 minutes, remove the tray and baste the chicken with the roasting juices and fat.
  7. Once fully cooked, take the chicken out of the oven, baste again, and leave it to rest for at least 30 minutes before carving.

Top Tips for Cooking a Whole Chicken

  • Bringing the chicken to room temperature before cooking is essential. It ensures even cooking and helps keep the breast meat juicy. Equally important is a proper rest after roasting, allowing the juices to redistribute.
  • Instead of olive oil, try soft butter for extra richness. You can also carefully push some under the skin of the breasts for even more flavour.
  • Once rested, lift the chicken with tongs and tilt it cavity-down to let the juices run out. These make the base of an excellent gravy.
  • To make a simple but sensational gravy, place the roasting tray over a medium heat. Stir in a tablespoon of plain flour and cook for a couple of minutes. Add a glass of white wine and some homemade chicken stock, then simmer gently for 10 to 15 minutes.
  • Save the carcass for stock, but be sure to remove the lemon from the cavity to prevent bitterness.

Recipe Ideas for a Whole Chicken

When it comes to whole chicken recipes, simplicity often wins. A classic roast with potatoes, carrots and buttered cabbage is hard to beat. Or opt for a lighter supper of roast chicken and green salad. Croutons made in the roasting tray are a clever, flavour-packed addition.

For something richer, Valentine Warner’s roast chicken with Dijon mustard sauce is a timeless option. For a bolder take, try Anna Tobias’s Jaffna-Style Roast Chicken, which brings spice and depth in equal measure.

Whole roast chicken also works beautifully cold the next day. Try it sliced in sandwiches, salads or a classic chicken pie.
